CITAS magazine opens its pages again to register research works and articles related to science, innovation, technology, the environment and society -especially in the field of education-; to continue, in this way, the editorial line drawn from its birth and fulfilling its objectives of being a means of dissemination of an academic, technical and scientific nature in which the different disciplines and fields of knowledge have a place, not only of the Faculty of Sciences and Technologies, but also of the Vice-Rector's Office for the Open and Distance University (VUAD), the Santo Tomás University in general and, as on this occasion, other entities and Institutions, which makes it a wide digital window, open to knowledge in the local, regional and national context.
